Wireshark Foundation

Wireshark is the world's foremost network protocol analyzer. It lets you see what's happening on your network at a microscopic level. It is the de facto (and often de jure) standard across many industries and educational institutions.

Wireshark development thrives thanks to the contributions of networking experts across the globe. It is the continuation of a project that started in 1998.

Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Originally named Ethereal, the project was renamed Wireshark. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. It is a measuring device used to examine what’s going on inside a network cable at a microscopic level. Wireshark is cross-platform, using the GTK+ widget toolkit in current releases, and Qt in the development version, to implement its user interface, and using pcap to capture packets; it runs on Linux, OS X, BSD, Solaris, some other Unix-like operating systems, and Microsoft Windows.
